move

This page should probably be moved to European Extremely Large Telescope (requires administrator) Rnt20 21:13, 13 December 2006 (UTC)

Agreed. Since the proposal seems totally reasonable and uncontroversial, I've gone forward and requested this on Wikipedia:Requested Moves ---Vladimir V. Korablin (talk) 16:34, 14 December 2006 (UTC)

42

this might be a bit far fetched, but did they chose exactly 42m because of the hitchhikers guide to the galaxy? no190.209.30.96 (talk) 00:17, 4 May 2010 (UTC)

Actually Yes - working as part of the team doing research into making the primary mirror segments, I have spoken to people involved with tendering bids for this project. 42 meter diameter was chosen for the H2G2 reference. Thunder Krieg (talk) 13:39, 25 February 2011 (UTC)

Material World Podcast

You may find this podcast an informative source of information http://downloads.bbc.co.uk/podcasts/radio4/material/material_20080605-1800.mp3 —Preceding unsigned comment added by 82.17.173.132 (talk) 14:07, 11 June 2008 (UTC)

Optical resolution

I am puzzled by the statement in the info box that the resolution depends on the target. As far as I know, the angular resolution is a feature of the airy disk which depends on wavelength, diameter, seeing conditions (turbulence, AO, detector readout time), and the spectroscopic resolution is a feature of the spectrograph (??) R. J. Mathar (talk) 13:37, 13 March 2011 (UTC)

I agree, this is incorrect, I removed it. 2pem (talk) 12:52, 30 November 2012 (UTC)

Construction start

When will E-ELT start contruction? —Preceding unsigned comment added by 123.24.225.130 (talk) 00:37, 15 April 2011 (UTC)

"The start of operations is planned for early in the next decade.[14]" -- so is it around 2013 or around 2023?

What kind of question is that? 2013 is this decade not the next one. 10 years for construction with the start at the end of 2012 is what I read, so around 2022 for first light.Martin Cash (talk) 11:45, 7 January 2012 (UTC)

Looks like first light is actually going to b 2024: http://www.eso.org/public/usa/news/eso1419/ 134.171.185.129 (talk) 23:18, 19 June 2014 (UTC) John

Video needs update

Could someone please update File:E-ELT Laser Guide Star.ogv from http://www.eso.org/public/videos/eso1150c/? I don't know how to do this, and the present version shows Ursa Major in the sky. --ἀνυπόδητος (talk) 17:31, 23 July 2012 (UTC)

Done, I uploaded the new version from ESO. — Preceding unsigned comment added by 2pem (talkcontribs) 13:01, 30 November 2012 (UTC)

Participating Countries and Costs

I recommend adding a list of participating countries plus the total costs of the project until inauguration in 2023 (about 1 billion euros AFAIK) — Preceding unsigned comment added by 83.82.71.89 (talk) 08:46, 9 May 2013 (UTC)

Time for an update?

"Funding was subsequently included in the 2012 budget for initial work to begin in early 2012."

As of July 2013, has construction begun? What is the progress? 69.125.134.86 (talk) 14:59, 7 July 2013 (UTC)

As of April 2014, there are reports suggesting that construction is now either imminent or already under way: see http://www.theguardian.com/science/2014/apr/20/spot-alien-life-european-extremely-large-telescope-chilean -- The Anome (talk) 15:24, 20 April 2014 (UTC)

Requested move 21 April 2017

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: No consensus.(non-admin closure) Winged Blades Godric 12:54, 7 May 2017 (UTC)



European Extremely Large TelescopeExtremely Large Telescope – The telescope name has been updated. Please see http://www.eso.org/public/teles-instr/elt/. Note, however, that the wiki page Extremely large telescope already exists, so we should be able to have both page (i.e., Extremely Large Telescope and Extremely large telescope). Jmencisom (talk) 09:36, 21 April 2017 (UTC) --Relisting. Andrewa (talk) 12:18, 28 April 2017 (UTC)

  • Postpone I think this proposal has come too soon. Per concerns above, it may just be the shortened name. We should wait to see if this is so or not. We can wait a few months to see if the change propagates, and if it is used by the majority of third party sources. -- 70.51.200.162 (talk) 05:30, 22 April 2017 (UTC)
  • Comment is "extremely large telescope" the correct generic name for this class of telescope? (or should it be called something else, like "30-meter class telescope" / "100-foot class telescope" / "20-50m (50-150ft) class telescope" -- 70.51.200.162 (talk) 05:34, 22 April 2017 (UTC)

Discussion

This raises a number of issues.

Should occurrences of European Extremely Large Telescope in sources also count as occurrences of Extremely Large Telescope? I think they should.

Is the capitalisation sufficient disambiguation? I think it is.

Other opinions? Andrewa (talk) 12:18, 28 April 2017 (UTC)

No, it cannot be counted that way, "European Extremely Large Telescope" (and E-ELT) should be excluded when trying to determine if "Extremely Large Telescope" (ELT) is the name to be used for this article -- 70.51.200.162 (talk) 06:51, 30 April 2017 (UTC)

Great job, ESO. See the previous move discussion for context and the conflict with Extremely large telescope. Maybe we can move Extremely large telescope to Extremely large telescopes (as it describes a class of telescopes)? I think we should move this article, but I'm not happy with the conflict. --mfb (talk) 14:25, 14 June 2017 (UTC)
